COMET P/1999 X1 = 2006 O1 (HUG-BELL)
D. Tibbets and G. Hug, Eskridge, KS, report the CCD recovery of comet P/1999 X1 at mag 18.6-18.7. Astrometry, new orbital elements (indicated correction of Delta_T = -0.12 day to the prediction; cf. MPC 48383, 2006 Comet Handbook), and an ephemeris appear on MPEC 2006-O03.

Further to IAUC 8471, the IAU Working Group on Planetary System Nomenclature has announced that the satellite S/2005 S 1 (cf. IAUC 8524) has been given the designation (and name) Saturn XXXV (Daphnis).


COMET 177P/BARNARD
Comet P/1889 M1 = 2006 M3 (cf. IAUC 8726) has been given the permanent number 177P (cf. MPC 57086).


THE EDGAR WILSON AWARD 2006
The Smithsonian Astrophysical Observatory announces that the 2006 Edgar Wilson Award for the discovery of comets (cf. IAUC 6936, 8554) is being divided among the following three individuals: Charles Wilson Juels (Fountain Hills, AZ, U.S.A.) and Paulo Renato Centeno Holvorcem (Campinas, Brazil) for C/2005 N1; and John Broughton (Reedy Creek, Qld., Australia) for P/2005 T5.


V2576 OPHIUCHI
D. K. Lynch, R. J. Rudy, C. C. Venturini, and S. Mazuk, Aerospace Corporation; R. C. Puetter, University of California at San Diego; and R. B. Perry, Langley Research Center, NASA, report 0.47- to 2.5-micron spectroscopy of V2576 Oph (cf. IAUC 8700, 8710) on June 14.4 UT using the VNIRIS spectrograph on the Lick 3-m telescope. This Fe II nova has broad (2700 km/s), flat-topped emission lines. There is very little reddening [E(B-V) = 0.25] and no evidence of dust in the nova ejecta. The object displays weak coronal lines from [S VIII] and [Si VI], and the unidentified features at 1.11, 1.19, 1.55, and 2.10 microns are present. Magnitudes for V2576 Oph: V = 13.9, J = 11.2, H = 11.7, K = 11.0.
